From 961be7ef6963806cb978ccd6acf6bf84b0c63346 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Thu, 22 Jan 2015 00:42:50 +0100 Subject: [PATCH] tpm/tpm_tis: Add missing ifdef CONFIG_ACPI for pnp_acpi_device This fixes a build failure if CONFIG_PNP is set but CONFIG_ACPI is not: drivers/char/tpm/tpm_tis.c: In function ?tpm_tis_pnp_init?: drivers/char/tpm/tpm_tis.c:912:45: error: invalid type argument of ?->? (have ?int?) acpi_dev_handle = pnp_acpi_device(pnp_dev)->handle; If CONFIG_PNPACPI is not set pnp_acpi_device is defined as 0 and thus accesing the handle is not possible.
